Greater India: How ancient trade routes built a vast, enduring cultural sphere across Asia

Nature · Published 30 September 2026 Swipe more like this →

In short: Greater India is not a single empire, but a historical cultural sphere spanning South, Southeast, and East Asia. For centuries, trade and religious exchange spread Sanskrit, Buddhism, and Hinduism, leaving an indelible mark on everything from architecture and language to the daily gestures of millions across the continent.

The concept of Greater India describes a historical region linked by the diffusion of Indian culture, religion, and administration starting around 500 BCE. Rather than a political entity, it functioned as a cultural sphere where Indian ideas merged with indigenous traditions. This process, often termed 'Indianization' by scholars like George Cœdès, saw Southeast Asian kingdoms adopt Sanskrit, divine god-kingship, and complex administrative systems, creating a resilient and stable political landscape.

The transmission of these ideas was multifaceted. In the north, Buddhist monasticism reached Tibet, Bhutan, and Central Asia, while in the east, texts and imagery traveled to China and Japan. In Southeast Asia, the influence was profound; the Ramayana and Mahabharata shaped local folklore, and Hindu-Buddhist architecture—such as the massive Borobudur in Java and Angkor Wat in Cambodia—rivaled the scale and aesthetic achievements of the Indian subcontinent. Even today, the legacy persists in syncretic religious practices, royal rituals in Thailand, and the widespread use of the Añjali Mudrā greeting.

Modern interpretations of the term have evolved significantly. In the 1920s, a group of Bengali scholars formed the Greater India Society, framing this history as a benign cultural expansion. While some later nationalists used these ideas to promote soft power and regional integration, others, like Sheldon Pollock, prefer the term 'Sanskrit Cosmopolis.' Pollock argues that this vast region was unified not by colonization, but by a millennium-long exchange of language and ideas, comparable to the role of Latin in Europe.
